k3d3d: A commercial (?) three-dimensional library created around May 2001. This DLL library was developed for easy display of basic three-dimensional primitives, and for simple deformation and animation. It is not known if any products using this library have been released. Cannot be released because it is commercial. (Development tools: Visual C++, OpenGL, STL) (The screenshots below are test applications for the library.)

zplayer: We applied Inverse Kinematics to the character animation viewer we created earlier. It uses a plugin developed with the MaxSDK to export the character's mesh, texture, physics, and motion information from 3D Stidio MAX. The exported data is in its own slightly compressed binary format. A feature of the program is that it runs on Linux as well. (Development tools: Visual C++, gcc, SDL, OpenGL)

The character with the skinning applied:

Inverse kinematics applied while walking. Ignore the strange(?) bones between the legs:

Motion retargeting sample video. You can see the same motion applied to characters with different leg lengths. Walking on an incline.

Creature01: A few shots while testing perpixel shading.
Model : 3D Studio MAX Character Studio sample file (39,742 polygons)
System : GeForce3, AMD 1GHz, 300x300x32, Windows 2000, Direct3D 8.x
Other : Bumpmapping, Diffuse+Specular, Perpixel Shading, Full Scene Antialiasing (4x), 50 frames per second

Creature02: This time, a moving pose. The number of bones is 20, and we are playing out Max's bee-catching motion.

Creature03: I tried adding shadows, and I used a shadow map for the shadows, and I also applied bumps, but it's a bit weird, something's wrong...:-) It's a 2-pass, so I still don't get the speed. (Geforce 3. 1 is about 10 frames per second on AMD....) Oh, and the polygon count was 39,742? Currently, the character and camera animations (linear, catmull-rom spline, squad, etc) are implemented. What do I need to implement now?

Face01: This is a model from a MAX sample. I tried painting the pupils and eyebrows myself, does it look awkward? I guess I'm having fun taking screenshots. I should probably refrain from making unnecessary updates. It's a shame there's no Pepsi logo on the forehead.

Face02: This is the anibal model in the max sample. It's a simple texture mapping with no real-time lighting. Of course, it's a render texture pulled from max's RenderToTexture, and the meshes were all converted with EditMesh in max and then set to texture coordinates at will. The polygon count is roughly 10,000, with more polygons than necessary for things like the eyes.

Kettle01: The kettle. Again, this is just a texture rendered with max's RenderToTexture and Light Tracer. It's a simple texture mapping with no real-time lighting at all. Ahhhh, I wonder if I could make a scene that actually renders in real time like this and not just a texture?

PinkyDaemon: I tried sprinkling in some monsters (pinky) from Doom 3. The tangent space bumpmap I made just wasn't cutting it, so I wondered what Doom 3 would have done, so I modified the nscemake tool from NeoEngine (http://neoengine.sourceforge.net/) a bit and loaded it into my program. I'm not quite there yet, but it gives me hope that the model and mapping can be fixed to some extent. :-) The first is a low polygon mesh (about 1700 polygons), the second is an example of normal mapping lighting, and the last is a texture. In fact, it looks like Doom 3 uses more detailed bumps, specularity, etc.
